Energy and habitat: Designing a sustainable urban ecosystem

As the world's cities grow so new ways of satisfying their demands for food and fuel resources will have to be found, especially in the third world where total fuel demands are expected to expand several fold in one generation. An ecological model for a future complex urban community is presented to illustrate the place of energy in a growing system and how habitat—the physical component—possesses life cycles interdependent with living species. Recycling, biomass fuels, telecommunications, marine living and the propagation of viable organizations are all elements that will enable the globe to sustain future expanding metropolises.
